PowerBlade reports bad values

brghena opened this issue · comments

After running continuously for several days, @bradjc has noticed that PowerBlade occasionally gives bad data. The data looks fine up until a certain point, then is totally invalid. On next packet it works again. See attached for dump of several incidents.

This seems like it could be a UART transmission issue where bad data is accepted. We might see if a checksum/crc fixes the problem.

449169e added checksums to all UART transmission. We'll test that and see if it fixes the problem

Yup. Fixed it
